Q1: What does the EC Billet PCV Valve do?
A: The EC PCV Valve controls crankcase pressure by allowing gases to exit the crankcase through a one-way check valve, preventing air from re-entering. This helps reduce blow-by, oil leaks, and pressure build-up.
Q2: What engines is this PCV valve compatible with?
A: It fits a wide range of engines including Honda GX200, Predator 212 & 420, Briggs & Stratton V-Twin, and most other small block or big block performance engines using 1/2” hose barbs.
Q3: Why is a check valve better than a basic vent fitting?
A: Unlike basic brass or aluminum fittings that allow air in both directions, the check valve only vents out, which prevents re-entry of air, helping maintain consistent internal pressure and performance.
Q4: Where should I install the PCV valve?
A: Install the valve at the highest point on the engine, usually the valve cover, and route it to an oil catch can that vents to the atmosphere. This setup ensures effective pressure relief.
Q5: Can I recirculate the valve back into the engine?
A: No. Recirculating the vented gases back into the engine (valve cover or crankcase) defeats the purpose of venting and can cause pressure build-up.
Q6: Is this valve compatible with methanol-fueled engines?
A: Yes. The all-aluminum construction and hard-anodized coating make it highly methanol-resistant, unlike plastic check valves which may degrade over time.
Q7: Do I need a specific catch can for this PCV?
A: No specific brand is required, but it should be an atmosphere-vented oil catch can. Avoid sealed or recirculating systems that prevent proper pressure relief.
